help
A current limitation of NEM (Non-Evict mode) is that code and data
sizes are derived from the requirement to not write out any modified
cache line. With NEM, if there is no physical memory behind the
cached area, the modified data will be lost and NEM results will be
inconsistent. ENHANCED NEM guarantees that modified data is always
kept in cache while clean data is replaced.
